beagleboard xm

This is the Kyosho Blizzard, a tracked remote control vehicle that’s a blast to take out in the rapidly retreating snowpack. [Antibore] was interested in performance testing the range of the thing. It includes a camera that streams video back to a tablet or smartphone. Both the video and the controls use WiFi for communications. As he expected, the rover loses control signal at about fifty meters, with the video has a disappointing twenty meter limit. His workaround is to saddle the crawler with a 3G bridge. Not a bad idea that may be feasibly completed with hardware you have on hand.

In this case he grabbed a Beagleboard-XM. It runs embedded Linux and has USB ports which is perfect for the other two parts of the added hardware: a Huawei E230 3G dongle and a WiFi dongle. This means no alterations to the rover were necessary. He set up OpenVPN and performed a few other tweaks. The WiFi signal is constant, as the transmitter and receiver are both attached to the rover. We just wonder about the latency of the 3G traffic. Let’s hear your thoughts on that in the comments below.

We would be remiss if we didn’t tie-in the potential of this hack. Previously this winter we saw a Kyosho with a 3D printed snow thrower attached to the front. More snow removal power, arguably unlimited range… you can do your entire block from the comfort of the couch. To the Future!

So you want to play some retro games on your BeagleBone, just load up Linux and start your favorite emulator right? Not if you’re serious about it. [Andrew Henderson] started down this path with the BeagleBoard-xM (predecessor of the BeagleBone Black) and discovered that the performance with Snes9X wasn’t quite what he had in mind. He got the itch and created a full-blown distro called BeagleSNES which includes bootloader and kernel hacks for better peformance, a custom GUI, and is in the process of developing hardware for the embedded gaming rig. Check out the documentation that goes along with the project (PDF); it’s a blueprint for how open source project guides should be presented!

The hardware he’s currently working on is a Cape (what add-on boards for the BBB are called) that adds connectors for original Nintendo and Super Nintendo controllers. It also includes an RTC which will stand in for the real-time clock features included in some cartridges (Pokemon Yellow). Also in the works is a 3D printed enclosure which would turn it into a portable, something like this other BBB portable hack.

Check out a demo of what BeagleSNES can do in the video after the break.

The Raspberry Pi is great if you’re looking for a cheap yet powerful computer running Linux, but let’s not forget all the other ARM dev boards out there. [Adam] spent some time this weekend putting together an Ubuntu distro for his Beagleboard XM to give it the convenience of a GUI and a whole bunch of drivers to get a lot of stuff done.

The Beagleboard XM is another high power ARM dev board that is a little more capable than the Raspberry Pi. With an integrated USB hub, LVDS LCD displays, and a camera board, the Beagleboard already has a lot of peripherals that are now only promised for the Raspberry Pi. The only problem with the Beagleboard XM is the state of drivers and software; a problem [Adam] resolved by bringing Ubuntu to the Beagleboard.

[Adam]’s distro comes with all the goodies a relatively high-powered ARM dev board should have: Python, scipy, numpy, and a few cool extras such as GIMP and Chromium. He says it’s a bit faster than the stock Raspbian distro on the Raspberry Pi, so if you’re looking for the best ARM/Linux dev board for your next project, you may want to give [Adam]’s distro a try.
